发布时间:2020-07-21 18:31:46 阅读: 来源:摩擦磨损试验机厂家

身份认证技术是维持现代社会运行的一项重要技术,目前常用的认证技术 如密码、指纹、签名等存在容易遗忘和伪造的缺点,因而需要加以改进。我们利用手指血管图像识别这一新型的生物特征识别技术,通过自制手指 血管图像采集装置,实现了模块化、多用途的基于手指血管图像识别的身份识 别终端。我们在终端上加上磁卡读卡器、屏幕、票据打印机等外设,制作了以 手指血管图像为密钥的POS 机。 用该终端实现的POS 机具有以下功能: 1. 读取银行借记卡、贷记卡中的卡号等信息2. 通过手指血管图像识别验证用户身份3. 输入消费金额并打印凭条4. 通过网络与远程数据库交换数据5. 新用户的注册功能The modern society features the authentication technology. The main authentication technology such as password, fingerprint and signature has the disadvantages of easy to being forgotten and forged, so it should be improved. In this paper, we provide a modularized and multipurpose authentication terminal based on the finger vein pattern recognition, which contains a finger vein camera 500 designed by ourselves. The equal error rate (EER) of the recognition is 2.11%, and the recognition time is less than 1s. We add peripherals such as magnetic card reader, the notes printer and the screen to the authentication terminal to realize the function of e POS implemented by this terminal have the following functions.1. Read information from magnetic cards. 2. Authentication via finger vein pattern recognition.3. Input of spend and prints of information related. 4. The exchange of data via network with remote database. 5. New user registration. linux操作系统文章专题:linux操作系统详解(linux不再难懂)
